OUT = Output, IN = Input, ANA = Analog Signal, DIG = Digital Output, ST = Schmitt Buffer Input,
TTL = TTL Buffer Input, XCVR = USB Transceiver, x = Don’t care (TRIS bit does not affect port direction or is
overridden for this option)
RC4 and RC5 do not have corresponding TRISC bits. In Port mode, these pins are input only. USB data direction is
determined by the USB configuration.
